Answer:
- The other leg is 82 units
------------------------
Given:
- a = 19,
- c =
, - b = ?
Find the missing leg, using Pythagorean:
- a² + b² = c²
- 19² + b² = 7085
- 361 + b² = 7085
- b² = 7085 - 361
- b² = 6724
- b =

- b = 82
N = number
n; n+2 (odd)
n(n+2) = 195
n^2 + 2n - 195 = 0
(n-13)(n+15)
n1 = 13 ; n2 = -15 (void)
13; 15 are the two odd integers
Answer:
A
Step-by-step explanation:
Add 3x^2 and 5x^2 now it = 8x^2
Add -8x and -4x = -12x
look at your answer choices the only one that has 8x^2-12x is A
Assuming that your own ticket is already secured.
From the 5 friends you can only choose 3.
The order in which these friends are chosen is not relevant. So this is a Combination problem.
Where the order is relevant the problem becomes a Permutation problem!
So the answer is 5 combination 3. = ⁵C₃
⁵C₃ = (5 * 4 * 3) / ( 3 * 2 * 1) = 10
You can take 10 groups of any 3 of your 5 friends.
Answer:
a. variable
Step-by-step explanation:
X = number of days a Lake Tahoe Community College math student is absent
X is a random variable.
A random variable is a variable whose value is a numerical outcome of a random phenomenon.
A random variable's possible values might represent the possible outcomes of a yet-to-be-performed experiment.
Random variables are often denoted with capital letter
s and they can be discrete or continuous.
